Quote: 100hp per liter without even touching the inside of the engine, what a great era this has been for engines.
X2 just when we thought adding 1/2" of cranckshaft throw to a big block was the way to go now these smaller engines are laying down some HP on pump gas and all the accessories bolted up.
So where is all the power from? Cylinder head technology and fuel injection programming...what else is making these engines more efficient than the predecessors? (70's era)
